The Airmar P66 is a reliable transducer that has been used by boaters around the world for years. It is designed to provide accurate depth and temperature readings, and is a crucial component for any fisherman. However, wiring this device can be a bit of a challenge, especially for those who are new to electronics. In this article, we will explain everything you need to know about the Airmar P66 wiring diagram, and provide you with some diagrams to help you get started.
What is the Airmar P66?
The Airmar P66 is a transom-mount transducer that is designed to work with a variety of fishfinders and depth sounders. It is capable of measuring water depth, water temperature, and boat speed. The device is popular among boaters because it is easy to install and provides accurate readings.
How Does the Airmar P66 Work?
The Airmar P66 works by sending out sound waves that bounce off the bottom of the ocean or lake. These waves then return to the transducer, which measures the time it took for the waves to travel to the bottom and back. This information is used to determine the depth of the water. Additionally, the Airmar P66 can measure water temperature by using a thermistor.
What Makes the Airmar P66 Unique?
The Airmar P66 is unique because it uses a broadband transducer. This means that it can send out a wide range of frequencies, which allows it to provide more accurate readings than other transducers that use a single frequency. Additionally, the Airmar P66 has a built-in speedometer, which allows it to measure boat speed without the need for a separate device.
Understanding the Airmar P66 Wiring Diagram
When wiring the Airmar P66, it is important to understand the wiring diagram. This diagram shows how the different wires should be connected to the transducer and the fishfinder. The Airmar P66 wiring diagram consists of five wires: blue, brown, white, green, and shield.
Blue Wire
The blue wire is used to connect the transducer to the fishfinder’s depth sounder. This wire sends the depth information to the fishfinder, which displays it on the screen.
Brown Wire
The brown wire is used to connect the transducer to the fishfinder’s temperature sensor. This wire sends the temperature information to the fishfinder, which displays it on the screen.
White Wire
The white wire is used to connect the transducer to the fishfinder’s speedometer. This wire sends the boat speed information to the fishfinder, which displays it on the screen.
Green Wire
The green wire is used to connect the transducer to the fishfinder’s power source. This wire provides power to the transducer.
Shield Wire
The shield wire is used to ground the transducer. This helps to prevent interference from other electronic devices.
Wiring the Airmar P66: Step-by-Step
Now that you understand the wiring diagram, it’s time to start wiring your Airmar P66. Here is a step-by-step guide:
Step 1: Mount the Transducer
The first step is to mount the transducer on the transom of your boat. Make sure the transducer is mounted correctly and securely, as this will affect the accuracy of your readings.
Step 2: Route the Wires
Next, route the wires from the back of the transducer to the location of the fishfinder. Make sure the wires are secured and protected from damage.
Step 3: Connect the Blue Wire
Connect the blue wire from the transducer to the blue wire on the fishfinder’s depth sounder. Make sure the connection is secure.
Step 4: Connect the Brown Wire
Connect the brown wire from the transducer to the brown wire on the fishfinder’s temperature sensor. Make sure the connection is secure.
Step 5: Connect the White Wire
Connect the white wire from the transducer to the white wire on the fishfinder’s speedometer. Make sure the connection is secure.
Step 6: Connect the Green Wire
Connect the green wire from the transducer to the power source on your boat. Make sure the connection is secure.
Step 7: Connect the Shield Wire
Connect the shield wire from the transducer to the ground on your boat. Make sure the connection is secure.
Step 8: Test the System
Once you have completed the wiring, test the system to make sure everything is working properly. If you have any issues, refer back to the wiring diagram and make sure all connections are correct.
